I like pizza.  So like many people in America, I tried food from different pizza chains to see if there was any food I would order from the company a second time.  Here's my opinions (and thus you may hear me shoving down pizza-shops you enjoy), but please discuss in this topic as well!

Papa Murphy's:  My favorite pizza hands-down.  You have to bake it, but that's part of what keeps prices cheap(er) and reasonable.  You get what you pay for--a rich pizza that makes your mouth water.  And nothing beats a Papa-Murphy's Chicken Garlic Gormuet Pizza

Papa John's: Okay, so this pizza is quite delicious.  When they say quality, they mean it.  But over the years, the prices have become completely overcharged.  Gone was the day when there was a "buy one, get one free" coupon.  I enjoyed the pizza while it lasted, but now I just can't afford it.

Pizza Hut: I enjoy the personal pizzas, which you can't get anywhere else.  Sometimes I want a pizza but there's only one night I can eat it since there's no refrigerator, and the personal pizza does the trick.  However, the pizza itself is nothing out of the ordinary in my opinion, and I don't like stuffed crust pizza.

Little Ceasers: My second favorite pizza.  And what deals you get!  Good pizza for extremely reasonable prices.  You can't beat Hot-and-Ready for $5 with anything except Papa Murphy's.  I haven't had the chance to try their wings yet, but I want to...I'm a huge wing fan, and $.50 a wing is always a good deal for me.

Domino's: My favorite pizza crust, because it has its own buttery-flavor in it.  But although the prices are reasonable, the pizza is like pizza hut--nothing out of the ordinary in my opinion.

Godfather's: I only liked it for its all-you-can-eat pizza buffet.

Indeed, nothing beats the pizza from the restaurant around the corner.

Papa John's: Okay, so this pizza is quite delicious.  When they say quality, they mean it.  But over the years, the prices have become completely overcharged.  Gone was the day when there was a "buy one, get one free" coupon.  I enjoyed the pizza while it lasted, but now I just can't afford it.

I gotta agree with you on that one. They got great pizza, but lately they've been turning into the premium brand. I only get their pizza now for special occasions.

Pizza Hut: I enjoy the personal pizzas, which you can't get anywhere else.  Sometimes I want a pizza but there's only one night I can eat it since there's no refrigerator, and the personal pizza does the trick.  However, the pizza itself is nothing out of the ordinary in my opinion, and I don't like stuffed crust pizza.

Problem with me is that I need more than a personal pizza to keep me going But anyways it's been awhile since I went to pizza hut because their farther away then dominoes, but I actually enjoyed their stuffed crust imo

Domino's: My favorite pizza crust, because it has its own buttery-flavor in it.  But although the prices are reasonable, the pizza is like pizza hut--nothing out of the ordinary in my opinion.

Ever since they've had the recipe change I've loved Dominoes even more. They're only 2 minutes away from my house so it's very convenient. Now for all those people who say that Dominoes uses ketchup and cardboard, when is the last time you had their pizza? It's not that bad as people say.

I hear the pizza in chicago is the best for deep dish. My dad is always disappointed because he compares the ones we get with his favorite in chicago. chicago aways wins.

There is this Chicago style pizza place near my home and I love it. The pizza is well over 2 inches tall when you have all of your toppings on there. When you take a bite the inside is like warm dough and is just delicious. Unfortunately my dad does not like deep dish and prefers thin crust

Round Table: Don't go here, the prices are outrageous. It is $14 for a small pizza that really isn't all that great. Even the personal pizza is $8 and is the size of a CD. 

Ballpark Pizza: My all time favorite. It is a local pizza restaurant that is extremely popular among sports teams. From 5 year old soccer players to high school teams this place is the best. The staff is great and almost everyone knows the owner. The prices are great especially on Thursday for the Thursday special: Two large cheese pizzas for $22 plus $1.50 per topping. Which is perfect because I have my track meets on Thursday afternoons so afterwards my entire team heads down there.

My favorite for a chain is probably CiCis a chain restaurant(buffet $5) that is very popular around here at least.They have lots of variety and all you can eat for $5. no deep dish though

I've heard of them, but they don't have any locations within 15 minutes of my house so I've never been there. I also forgot to mention New York style pizza. And I mean real authentic New York City pizza. It is really good. New York pizza if you didn't know is baked in a coal fire oven giving it a unique taste. Proper eating procedures call for you to fold the slice in half that way the cheese won't fall off.

Its all about Pizza My Heart Its California local though, so not everybody gets to have their amazingness

nothing is better than small non-chain restaurants in down-south-inbred-land Pax-river Maryland.  Always look for one called something like 'Luigi's pizza' or 'Pizza by Luigi' (though as you might know from the office, never get anything from something with 'Pizza by' in the title...)

proof.

We all know that specialized resturants with no chains have the best pizza.  But please keep discussion limited to pizza chains.

I think Little Ceasers is my favorite chain, but I've only had it once since my family moved away from one fours years or so ago.
Pizza Hut is probably my second favorite.
